Application filed Maya, 1919. Serial No. 296,027.

To all whom it may concern:

Be it known that I, CRoNIN M. BUR- DETTE, a citizen of the United States, residing' at W est Chester, in the county of Chester and State of Pennsylvania, have invented a new and useful Gone-Puller, of which the following is a specification.

-My invention is designed especiallyfor placing and pulling the cones used in. the bowls of centrifugal separators, but it will be understood that it is not limited to such USO.

line 7 x of Fig. 6.

The characteristic features of the inven-. tion are comprised in its means for effecting an engagement with a device set or to be set in a cavity, as the interior of a tubular bowl or the like, and in pulling such device from" its engagement by a turning movement which effects a wedging action whereby it is moved longitudinally.

In its preferred form, the mechanism comprises a handle or shaft provided with a stem terminating in a bearing having helical wedging segments, in combination with a spring pressed sleeve movable on said stem, provided with wedging segments coacting with the segments aforesaid to effect a longitudinal movement of said sleeve against the action of the spring, and clutching means for effecting an interlocking engagement with the device to be manipulated.

In the accompanying drawings, Figure 1 is a broken sectional elevation of the top of a separator bowl in combination with my improved mechanism in engagement with a circular division wall or cone in operative position in the bowl; Fig. 2 is a view of the same illustrating a second position of the mechanism and cone which has been detachedfrom its engagement in the bowl by turning the handle or shaft of the mechanism; Fig. 3 is a top plan view of the detached cone; Fig. 4 is a side elevation of the detached cone; Fig. 5 is a top plan. view of the cone manipulating device or puller; Fig. 6 is a longitudinal sectional elevation taken on the line 6 6 of Fig. 5, and Fig. 7 is a sectional view taken on the The mechanism illustrated in the drawing comprises a tubular bowl 1 having a socket 1 in the head thereof, in combination with a cone or circular partition 2 having 2.

head 2* set therein, the cone head containing an oblong opening 2 having the in- Wardly projecting flanges 2 on opposite sides thereof. 7

The puller or extracting and replacing device of my invention comprises the handle orshaft 3 provided at an end thereof with a stem 4 having a head 5 on which are helical segments or wedging jaws 5 A sleeve 6 is placed on the-stem 4 and is provided with the helical segments or wedging aws 6 adapted for engagement with the similar aws 5 with the oblong flange or oppositely projecting flanges 6 adapted to pass through the opening 2 there to be turned 111130 lapping engagement with the flanges 2, with the circular flange 6, having a diameter larger than the distance between the flanges 2 and with the oblong section 6 between the parts 6' and 6. A coiled spring 7, disposed on the shank 4 between the handle 3 and the sleeve 6, acts to move the latter along the shank and press the jaws 6 against the jaws 5.

In operation, with the head 2 of the cone 2 set in the socket 1 of the bowl 1, the extracting device is inserted and initially occupies the position illustrated in Fig. 1, the part 5 bearing against the top of the bowl and the section 6 registering with the flanges 2 which now lie between the flange 6 and the plane of the flanges 6 The handle or shaft 3 being turned to the right,

the section 6 engages the flanges 2 and the flanges 6 lap the flanges 2?, the turning movement of the sleeve 6 relative to the cone 2 being limited thereby. Upon further turning the handle 3, the jaws 5*- are moved angularly with relation to the jaws 6 which retracts the sleeve 6 on the shank 4 against the action oft-he spring 7, the cone 2 being thereby detached from its frictional engagement in the socketl and being removed from the bowl by withdraw- To replace the cone in the bowl, such cone may be engaged on the extracting device with the flanges 2 in registration with the oblong section 6 and in bearing engagement with the flange 6. The tool with the cone thereon is then thrust into the bowl so as to seat the head of the cone in the socket. If necessary, the tool or extracting device is turned so that the flanges 6" will pass through the opening 2 when such tool can 7 be withdrawn.

It will be understood that for the purpose of assembling the device, the handle 3 may have its stem 4- screwed therein after the sleeve 6 and spring 7 have been placed on the stem, or the head 5 may be fixed on the stem after the spring and sleeve have been placed thereon.

Having described my invention, I claim 1. In a device of the character described, a handle having a stem provided with a wedgi -ng jaw, in combination with a sleeve on such stem, said sleeve having a wedging jaw coacting with said wedgingfljaw first named, and means for limiting the turning movement of said sleeve with said handle, whereby said jaws move said sleeve longitudinally on said stem.

2. In a device of the character described, a sleeve having means for interlocking it with a device to be operated thereby, in combination with a handle having a part thereon extending through and adapted to turn in said sleeve, said sleeve and part having coacting devices whereby said sleeve is adapttudinally by turning said handle relatively thereto.

4:. In a device of the character described, the combination with an article having an aperture therein, of a handle having a part with a head thereon adapted to pass through said aperture, and a sleeve movable on said part and having a clutching member adapted to pass through said aperture, a member adapted to bear against said .artic'lewhen said sleeve is turned and a member coacting with said head, whereby said sleeve is movable longitudinally to pull said' d'evice on turning said handle,

In testimony whereof I have hereunto set my name this 30th day of April, 1919.

C. M. BURDETTE.
